3 Claims.

The invention relates to foot arch supports and has for an object toprovide an improved support for both the metatarsal and longitudinalarches of a human foot. The invention has for another object to providea support which provides clearance for the inner longitudinal arch. Theinvention has for a further object to so construct the support that ithas an extended face for supporting the foot and substantially relievingthe heel of load.

These and other objects of the invention will become apparent from thefollowing description, taken in connection with the accompanyingdrawing, in which Figure l is a plan view of a foot arch supportembodying my invention, a foot, shown by dotted lines, beingsuperimposed;

Figures 2, 3, 4:, and 5 are cross sections on the lines 2-2, 3-3, 3- 3,and 5-5 respectively of Figure l.

In general, l is the foot arch support which is designed to support theanterior metatarsal arch and the outer longitudinal or weight bearingarch of the human foot 2, shown in dotted lines in Figure 1. Thissupport is also designed to provide clearance for the inner longitudinalor spring arch of the foot so that the latter may function normally. Thesupport is solid and may be formed of a number of. materials and, asshown, is formed of a light metal, such as aluminum. The lower face ofthe support is flat while the upper face is rounded. The support, asillustrated in the present instance, is located between the upper andlower leather layers 3 and 4 respectively, which are cemented togetherand form an insole. The portion of the upper insole layer engaging theupper face of the support conforms to the contour of the upper face. Itis apparent that the support might also be built into the shoe betweenthe insole and outsole or located on the insole and covered.

The support is a generally L-shaped member having the longitudinal part5 and the integral transverse part 6. The support is so located that thelongitudinal part supports the outer longitudinal or weight bearing archof the foot and clears the inner longitudinal or spring arch of the footand the transverse part supports the anterior metatarsal arch of thefoot. The outer edge of the longitudinal part is preferablysubstantially straight and the upper face of this longitudinal part ispreferably rounded transversely of the foot and tapers downwardly tomerge with the lower face at the inner edge, as

shown in Figure 3. The transverse part 6 extends inwardly of the footbeyond the longitudinal part 5 and its toe edge is curved and its upperface is rounded both longitudinally and transversely of the foot, asshown in Figures 2, 4, and 5, the greatest height being approximately atthe middle of the transverse part.

The longitudinal part 5 is also formed at its heel edge with theintegral extension I which extends inwardly of the foot. The heel edgesof the longitudinal part and the extension register and are positionedto terminate adjacent the heel of. the foot, the arrangement being suchthat the support has an extended supporting face for the foot adjacentthe heel and substantially relieves the heel of load.

For additionally securing the support in proper position, thelongitudinal part 5 near its heel end is formed with the countersunkhole 8 through which may extend a suitable riveting member 9 which maybe clinched over against the lower insole layer 4.

What I claim as my invention is:

1. A foot arch support, comprising a transverse part for supporting theanterior metatarsal arch of the foot, the upper face of said part beingconvex longitudinally and transversely of the support, and alongitudinal part of less width than said transverse part for supportingthe outer longitudinal arch of the foot, the upper face of. saidlongitudinal part being convex transversely thereof.

2. A foot arch support, comprising a generally L-shaped member having atransverse part for supporting the anterior metatarsal arch of the foot,the upper face of said part being convex longitudinally and transverselyof the support, and a longitudinal part for supporting the outerlongitudinal arch. of the foot, the upper face of said longitudinal partbeing convex transversely thereof.

3. A foot arch support, comprising a longitudinal part adapted to belocated to support the outer longitudinal arch of the foot, and anintegral transverse part at the toe end of said longitudinal partadapted, to be located to support the anterior metatarsal arch of. thefoot, the upper faces of both of said parts being convex transversely ofthe parts, said transverse part extending inwardly beyond saidlongitudinal part and said longitudinal part having at its heel end. anintegral inward extension.
